摘要:
]用模拟实验方法研究了天然沸石活性覆盖层控制底泥氮磷释放的影响因素(如温度、天然沸石厚度以及pH值等),结果表明:1)厌氧状态下,天然沸石覆盖层可以有效地控制总氮和总磷的释放;2)温度越高,底泥总磷的释放量越大,沸石层抑制底泥总磷释放的效果越差;3)天然沸石层厚度与底泥总磷释放相关性不明显;4)温度的高低及沸石层的厚度对沸石层抑制底泥总氮释放的影响不大;5)对上覆水进行酸碱性的调节,有利于提高沸石层对总磷、总氮的控制效果,酸性条件下吸附效果更佳
Abstract:
The influencing factors(temperature,thickness and pH value)of natural zeolite barrier to immobilize phosphorus and nitrogen release from sediments were researched,and the results showed that:1)zeolite barrier could effectively control the N and P release from sediment under anaerobic conditions;2)the sediment TP release increased with temperature,but the sediment TN release had no obvious relativity with temperature;3)the thickness of natural zeolite barrier had no obvious effect in controlling P release from sediment;4)the temperature and thickness of natural zeolite barrier had no obvious effect in controlling N release from sediment;5)under the acid(pH=6)condition,the adsorption effect was better than pH=8
